Problems solved by technology

These problems cannot be completely solved through debugging in actual mold manufacturing, which will not only reduce the quality of automobile panel products, but also affect the mold manufacturing cycle
Secondary deep drawing is an effective means to solve this problem, but adding a drawing process means adding a set of stamping dies and increasing development costs

Embodiment Construction

[0032] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0033] Such as figure 1 As shown, the present invention specifically relates to a drawing stamping die, including an upper die 1 and a lower die base 9, and the lower die base 9 is provided with a step-by-step drawing forming process from shallow to deep through cooperation with the upper die 1. The multi-action drawing forming mechanism. Through the multi-action drawing forming mechanism, when the pressed product is drawn and stamped with different drawing depths, it can be drawn and formed step by step from shallow to deep, so as to avoid insufficient forming and product quality problems.

Abstract

The invention discloses a drawing stamping die and its multi-motion drawing process. The drawing stamping die includes an upper die and a lower die base. Multi-action drawing forming mechanism for step-by-step drawing forming from deep to deep. The drawing and stamping die of the present invention realizes multiple formings in one process, solves the problem of drawing and forming of such parts, and saves investment in die development caused by additional processes. It is conducive to improving the level of mold design and manufacturing, and at the same time can reduce production costs for the automobile industry and bring considerable economic benefits.

Description

technical field [0001] The invention belongs to the technical field of stamping forming dies for automobile cover parts and drawing processes thereof, and in particular relates to a drawing stamping die and a multi-motion drawing process thereof. Background technique [0002] The working principle of the conventional drawing die is as follows: in the mold opening stage, the upper mold is lifted up, the lower mold does not move, and the air ejector rod pushes the blank holder upward for a stroke, at this time, the blank is placed on the blank holder; Die stage: the machine tool drives the upper mold downwards to close the blank holder to press the material, and then the machine tool drives the upper mold and the blank holder downward together to close the lower mold to complete the drawing forming process; during the entire forming process , the air ejector rod maintains an upward force on the blank holder. [0003] Conventional drawing die structures are widely used in auto...
